Hi Guys, I thought ER and ZR SFP+ optics were not available (yet) due to power and cooling "challenges". However on this site: http://www.excelight.com/products/datalink/sfpplus.asp They offer both ER and ZR SFP+ optics. Has anyone used or tested with these? If so with which equipment? Or have you found other vendors of these optics? Thanks in advance, Bas

Last time I checked there was an ER SFP+ optic in acceptance testing at one major network vendor. That was about a year ago so it would not surprise me if there was one available. The problem was heat dissipation in the small form factor. The optic module gets hot and doesn't live long. George

They aren't (yet), these are vaporware. Many amnufacturers are close to having reliable 40km optics, and several are making 20km+ overpowered LRs, but ZR and DWDM are still a ways out. There are also some CWDM units in the works, but because SFP+ doesn't support onboard EDC you are limited by dispersion to 10km in the traditional 8ch 1470-1610nm CWDM space over SMF28. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
